Applcaton'le January 17, 1918. Serial No. 212,196.

T 0 all whom t may concern.'

Be it known that I, JOHN I-I. CRUMB, a citizen of the` United States, residing at Lawrence, in the county of Douglas and State of'Kansas, have invented a certain new and useful Improvement in Car-Doors, of which the following is a specification.

My invention relates to improvements in car doors.

It is particularly grain door.

Gne of the objects of'my invention is to provide a car door withwhich the usual eXtra boards for closing the lower portion of the doorway may be dispensed.

A further object of my invention is to provide a car door of novel construction, which may be easily opened.

Still another object of my invention is the provision of a car door,-the upper portion of which is arranged to swing outwardly and downwardly from the 'closed position, so as to permit loading and unloading of the car while the lower portion of the door is closed.

Still another object of my invention is the provision of a car door of novel construction which may be easily opened and closed and which may readily be slid to and from the closed position without interference with the side of the car in case that the latter is bulging.

My invention provides further novel means for securely fastening the lower end of the door in the closed position.

Other novel features of my invention are hereinafter' fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention,

Figure 1 is a front elevation of my improved car door shown mounted in the closed position on the body of a boX car, a portion of which is shown.

Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1.

Fig. 3 is an enlargedV horizontal section on the line 3-3 of Fig. 1.

Fig. '4 is a vertical sectional viewon the line 4 4 of Fig. 1.

Fig. 5 is a vertical sectional view, showing the upper section of the door in the depending open position, and showing the lover seetion of the door released..

adapted for use as a F ig. 6 is a front elevatiompartly broken away of a portion of the 'upper section of the door and a portion of the mechanism for locking the upper section, the locking mechanism being shown in the unlocked position.

Similar reference characters designate similar parts in the different views.

1 designates an ordinary box car body having the usual side doorway 2 having secured respectively to its sides seat strips 3 against which are adapted to bear a sliding door comprising an upper section 4 and a lower section 5, the latter being provided at its upper end with' a transverse bar 6 hav ing projecting ends which extend beyond the doorway at opposite sides thereof and which are respectively secured to the lower ends of two depending bars 7, the upper ends of which have respectively rotatably mounted on them supporting rollers 8 which are supported by and adapted for traveling engagement with a horizontal track 9, which is secured to the car body 1 above the doorway 2.

The lower edge of the upper door section 4 is hinged to the bar 6 by hinges 10, in a manner such that the upper section ymay be swung between the bars 7 from the closed position shown in Fig. 4, to the depending open position shown in Fig. 5.

For locking the upper section in the closed position in which it will bear against the strips 3, any suitable locking mechanism may be provided. In the drawings, I have illustrated for this purpose the following described mechanism.

Fivoted respectively on horizontal pins 11 to the outer side of the upper door section 4 are two locking levers 12 and 13, the outer ends of which are respectively slidably mounted in guide plates 14 and 15, and which are respectively adapted to engage locking plates 16 and 17, which are secured to the car body 1 above the doorway 2.

For simultaneously swinging the levers 12 and 13, there is provided a lever 1B which is pivoted by a horizontal bolt 19 to the door section 4 at the longitudinal center thereof. The upper end of the lever 18 is provided with a horizontal pin 20, which extends through and is slidable in longitudinal slots 21 and 22, provided in the inner ends of theA levers 12 and 13.

locking pin 25, which is adapted to be in-` serted through a hole 26 provided in a horizontal arm of a T-shaped plate 27, Fig. 5,

which is secured to the outer side of theV door section 4.

Hinged to the bar 6 is a hasp 28, Fig. 5, having a hole 29 in its Vfree end, which is adapted to receive the locking pin 25, as is best shown in Fig. 4 and also in Fig. 1. The lower end of the pin 25 is Vprovided with a transverse hole 30, Fig. 1, which is adapted to receive a detachable locking wire 31, which may be provided with the usual lead seal 32.

' By removing the seal 32 and wire 31, the pin 25 may be removed upon which the lever 18 may be swung from the position shown in Fig. 1 to the unlocked position shown in Fig. 6, after which the upper door section 4 may be swung outwardly Jfrom the closed position shown in Fig. 4 to the depending open position shown in Fig. 5. Y Access may now be had through the upper portion of the doorway 2 to the interior of the car for loading or unloading.

For releasably securing the door adjacent to the hinge joint between the upper and lower sections, the projecting ends of the bar 6 are provided with transverse holes, in which are detachably placed respectively two bolts 33, which are adapted to be insertedy through holes, provided in the car Vbody 1 at opposite sides of the doorway 2,

, and to Yrespectively engage two nuts 34 which are mounted in the car body 1. y

By tightening the bolts 33, the lower sec tion 5 may be firmly held at its upper end against the seat strips 3. Uponremoving the bolts 33, the lower section 5 is adapted to swing outwardlyby gravity from the closed position, shown in Fig. 4 tothe Vposition shown in Fig. 5. The door may now be readily slid to the open position on the track 9, regardless of any bulging of the side of the car.

For locking the lower end of the door in the closed position, there is pivoted by a horizontal pin 35, which is secured to the car body 1, at one side of the doorway 2, a locking bar 36, which is adapted to be swung from the` open position shown in dotted lines in Fig. 1, in which it is resting in a bracket 37 secured to the car body, to the horizontal locking position shown in Fig. 1, in which it extends transversely across the outer side and beyond the lateral edges of the lower door section 5, as shown in solid lines in Fig. 1. In the locking position, the bar 36 rests in two brackets 38, which are secured respectivelyV to theouter side of the car body at oppositeV sides respectively of the doorway 2.

For locking the bar 36 in the locking position, there is provided a locking member 39 which ispivoted by a horizontal bolt 40 to the outer side of the lower door section 5 above the bar 36, as shown in Fig. 1. lhen the member 39 is swung'downwardly to the vertical position, its lower end engages the upper side of the bar 36 and holds the latter fromV being swung upwardly from the locking position. Y

For holding the member 39 in the locking position, it .has secured to it a hasp 41, which is adapted to engage a staple 42 secured to thev outer side of the bar 36 and adapted to receivea padlock 43 ora seal, as the case may be. Y

By removing the padlock or seal43, the

4hasp 41 may be released from thestaple 42, upon which the member 39 may be swung to the horizontal position, thus permitting the bar36 to be swung to the position shown in dotted lines inFig. 1.

The lower door section 5 is provided near its lower end with a transverse discharge hole 45, which is adapted Vto be closed by a sliding door 46, and which is also adapted to be covered by the pivoted member 39, when the latter is in the locking position shown in Figs. 1 and 4, and also in Fig. 3.

When the member 39 is swung to the` horizontal position, and the sliding door 46 is moved vertically upwardlylto the open position, the grain at the inner side of the lower door section 5 Vmay be discharged through the hole 45, thus relieving the pressure against the lower door section, following which the bar 36 may Vbe swung to the unlocked position, thus permitting the lower door section to swing outwardly.

I do not limit my invention to the structure shown and described, as modifica-tions, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:

1. In a car, a car body having a doorway, two brackets secured to the car body, a door for closing said doorway having a transverse hole adjacent to its lowerend, means for supporting the door from the car body so that it may swing outwardly from a closed position between said brackets, a locking bar movable vertically to Vand from engagement with said brackets at the outer side of said j door for holding the door closed, anda locking member pivoted to said door and movable to and Jfrom a position in which it will simultaneously cover 1aid hole and engage the upperside of said 2. In a car, a car body having a doorway, a door having a transverse hole adjacent to its ,lower end, means for supporting the door from the car body so that the door canswing outwardly from a position closing said doorway, a locking bar pivoted to the car body and adapted to Swing to and from a locking position across the outer side of said door, and a locking member pivoted to the car door and arranged to swing to and from a position in which it will close said hole and engage and hold said locking bar in the locking position.

In testimony whereof I have signed my name to this specification.

JOHN H. CRUMB.
